When you try to uninstall an application or node, you might
encounter problems. This topic suggests ways to resolve uninstallation
problems.
What kind of problem are you having?
If none of these steps fixes your problem:
- Make sure that the application and its web and EJB modules are
in a stopped state before uninstalling.
- If you are uninstalling or installing an application using wsadmin,
make sure that you are using the -conntype NONE option
to invoke wsadmin and enable local mode. To use the -conntype
NONE option, stop the hosting application server before uninstalling
the application.
- Check to see if the problem has been identified and documented
by looking at the available online support (hints and tips, technotes,
and fixes).
- If you don't find your problem listed there, contact IBM support
After uninstalling application through
the wsadmin tool, the application throws "DocumentIOException"
If
this exception occurs after the application was uninstalled using
wsadmin with the
-conntype NONE option:
- Restart the server or,
- Rerun the uninstall command without the -conntype NONE option.
The removeNode command
does not remove the installed application from the deployment manager
If
the applications were installed indirectly using the addNode command
with the -includeapps option, then removeNode will
not uninstall them, since they may be in use by other nodes. These
applications must be explicitly uninstalled, for example through the
administrative console.
I cannot display
the syntax for the removeNode command
Unlike the addNode command,
the removeNode command is valid with no parameters,
so executing it will execute the operation, that is, remove the node,
without displaying the command syntax.
To see the valid options
for removeNode, run removeNode -? or removeNode
-help.
